[lustre-discuss] Lustre and OFED

[Jeff Johnson]

Eli,

The biggest driver is usually the drivers. Newer Mellanox hardware not yet
supported, or supported well, by kernel IB. Way back in the days of old
there were some interoperability issues where everything (clients and
servers) needed to be the same drivers and libraries but much of that was
cleaned up. There could be situations where OFED is needed on the server
side to support something under the Lustre layer like OST or MDT block
devices via iSER, SRP, NVMeF, etc.

There may be other reasons but those are off the top of my head.
